Be it io'wn that 1, WILLIAM F. lnnoimo, "b of the United of America,

resit mg Springfield, in the counly oi llmnpden and Commonwealth of Massachusetts. have invented certain wow and useful. lmpiovemenis in Trim oi which the 'ioL lowing is E--SI)Cll'lCiLt10I1.

This im 'oiilgion relates to ini novomonts 10 in trucks that are in common IN-ll in manufacturing establishmonts. eithoi' as a: l'miloi' for nl'lnohmenl to a motor firm-k, as an (lif' trio-ally opoi'a'ted truck or for placing: with ales oi ililloront lii'mls lhoi'oon as. for 0:0

The ohjvot of inupriagont invention IS to PHWUlP H truck that is vefy rigidly nnulo nml ono that win ho COHSLTUClZGd at small oxponso. 'lho invon- 'tio'n broadly C(rllY-llflQW-Wl vompi-isios in localing pm'ollolnml espaoml hoams pH-d omhlv of channel. iron construction on owl 110:] l. lho outer edge of the plati m'ninn(l on the nmlor side of tho some and, in the some swunhetwon those, beams locating the Supporting casters or wheels, thoso at tho loi-ivnrilonll of the truck heingoi the swivel ty 2 and those at tho rem GIHl of the truck being fixed so that the wheels always i'otal o in the space hocwoon the parallel booms.

'lho present invention is; pai'iionlm'ly adapted to ho 113ml in connection with ohi'ating trucks by running" or pushing tho upper platform of tho (ltVfiiilflQ trunk under 'llfi floor oom-ii ---l-- :mil in the spamislio cl'm'nnol irons in lihe sumo inn-w no? that, an devoting firm-l; is; run nnilm' iiho usual oo wl'iicli the :olzivloo lo ho transferred placed.

The pi'eseni; truck, therefore, servos iho doublopurpos of trailer and also no skid dev ce Referring to the diowii'igsi Figure} is a bottom planiview of tho truck showing, the beams m ll custom so cured thereto, the swivelerl inst-61's :n'; the

Referring to the drawings in detail; the

boards 02" planks componinp; the bottom or platform, are, inmliootocl at 1.. Secured to the under side of tho Plllllifllllfi are channel irons Q flllll 3. thrflan g i. portipns 3of the channel being arranged or loonlzotl slightly hock oi the. edge .4. of thP planks. Those chmmol irons are spaced from each other.

Tlltfifi haackots, as: shown, are hollwl to tho lower (images of the olm'nnol irons m: :shown. Tia will ho noticed that by attaching ill'lCFJB hi'zuliofin to the lung Fl they will he spaced. illi'VETlL'll from tho otlgo 4i ()i' niclo of the platform who'rowhich, lilgo tho ln'm-lzoi; 3 mo hol .fl to both of (ho (*hnnnol irons and rlizooiily i'oo vo iho lone] which is ovonly (lifih'ihhfiori on A iIC-f r-hunool irons-. and l'hoeto hi': (1mm m'e spin-ml inwm'i'l from llw M 11: 4 of the platform lllfl tho hrai'rkoi's h. fihziii; 9 support; the Wheels;

Q. in trucks oi this kind it is common to holl; the hmrhox's which carry the lOllBlH on lo the siilo oi the lltiflll'lF-l with the result that on m'ioq'ual lovol'zigo results and often the. brackets are broken and twist from tho supporting beams or irons.

Tn tho present invention the lozul is carried and evenly distributed by the shafts atv porting rollers are used jin'this class or type of trucks referred to in my invention and. to place the supporting rollers between parallel arranged beams whereby the supporting roller-s will be at all times in the line,

of draft and the load equally supported by each beam.

It will be noticed thatvin the present invention the line of draft on the truck passes directly through a vertical'plane that is located in the space 5 between the beams as indicated by the arrow 10, and that the load is equally distributed on the oppositely located brackets whiclrare secured as stated, to the lower flanges ot' the channel irons as indicated by the bolts 11.

It will also be noticed that the supporting beams will equally support the load when the swiveled casters 7; are turned as shown in Fig. 1.

A suitable handle is shown at 12.

hat I claim is:

In a truck for commercial purposes, the combination with the platform thereof, of two pairs of channel iron supporting beams secured to the under side of the platform and near the outer edges of the same, said beams being spaced in parallel relation to each other and extending the entire length of the platform, supportingrollers located at the ends of the beams midway in the space between said beams, the forwardv rollers or casters being of the swivel type and the rear casters or rollers of the fixed type, whereby the load is borne equally by the two pairs ofbeams and in line with the motion of the truck, and whereby a space between the innermost beams is provided for receiving an elevating truck.
